E LIJAH' LIND'SLEY, OF NEENA-H, WISCONSIN. Letters Patent No. 84,557,dated December 1, 1868.

IMPROVEMENT IN THRESHINQMACHINES.

The Schedule referred to in these Letters Pltmtand making part of thelame.

To all whom it may concern Be it known that I, ELIJAH Lmnsnnr, ofNeenah, in the county of Winnebago, and in the State of Wiscousin, haveinvented certain new'and useful Improvements in Threshing-Machines anddo here by declare that the following is afull, clear, and exactdescription thereof, reference being bad to the accompanying drawings,and t0 the letters of reference marked thereon.

The nature of my invention consists in the construction of a sieve forthreshing-machines, and in ananging the same so as to properly thresbthe grain with ease and dispatch.

In order to enable others skilled in the art to which my inventionappertains, to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawings, whichforma part of this specification, and in whicb Figure 1 is a plan viewof the machine with the sieve removed, shown in red lines;

Figure 2, an end elevation of the same with the sieve in; and

,Figure 3 is a side view of the sieve.

A represents a frame, of suitable dimensions, in the sides of which areblocks or ears, a (1,. l r

In these blocks the shafts B B have their bearings, each shaft beingprovided with two rollers, G O, on which rollers the sieve D rests Thesieve D is round, and formed in the shape ofa cylinder open at bothends, its sides being made of wire, interwoven so as to form meshes ofsuitable size to allow the grain to pass through,- and inside of thesame, in the ribs of the sieve, is secured a number of bent teeth, 1' i,which, when the sieve revolves, efi'ectually separate or shuck thegrain.

The sieve D is placed on the four rollers O O, and a band, E, connectsone of the shafts, B, witha shaft,

F, on the outside of the frame A, said band passing around pulleys onboth shafts. The shaft F being revolved by any means desired,communicates motion to the said shaft B, and, by friction, revolves thesieve, the ends of the sieve, which rest on the rollers, being, for thatpurpose, surrounded by metal bands".

At the rear end of the frame A, which is placed near the fan, is aninclined board, G, which'points into the sieve D, and is provided at itslower end with a number of teeth, I) b.

Below this inclined board is a series of wind-boards, H H, which arepivoted in the sides of the frame A, and can be turned up or down bymeans of straps I I attached to the same, and passing through the frame.By this means, the current of air from the fan to the sieve can beeasily regulated, at the pleasure of the operator.

Under the sieve D is aninclined board, J, which slants towards the rear,and on which the grain falls, as it is separated through the sieve.

The shock, &c., passes out through the front end of the sieve into aspout, K, which is suspended on one side of the frame A by wire d, andprovided at the other end with two rods, 0 c, which pass through theother side-of the frame, thus supporting this end.

The spout K is further connected, by means of a rod, J; to a wheel, L,on the shaft F, so that when this shaft is turned, the spout obtains areciprocating motion un-v der the front end of the sieve, whichfacilitates the passing out of the shuck and other stuif separated fromthe grain.

Having thus fully described my invention,

What I claim as new, and desire to secure by Let ters Patent, is-- 1.The cylindrical sieve D, provided with bent teeth t '5 along its ribs,and resting on four rollers, O O, which are placed, one near each end ofthe two shafts B B, and one of said shafts being turned, imparts thenecessary rotary motion to the sieve, substantially as herein set forth.

2. The arrangement of the frame A, sieve D, and
